第3题:

(c) You have been making preliminary inquiries regarding matters arising from the previous year’s audit of Di Rollo.

It has been revealed that no action has been taken in response to the management letter prepared by the previous

auditors. Di Rollo’s management has explained that this was because it was ‘poorly prepared’ and ‘unhelpful’.

Required:

Briefly describe various criteria against which the effectiveness of a management letter may be assessed.

(7 marks)


正确答案:
(c) Management letter effectiveness criteria
Tutorial note: Candidates at this level must know that a management letter is a letter of weakness (also called post-audit
letter). NO marks will be awarded for consideration of any other letters (e.g. management representation letters, engagement
letters).
■ Timeliness – a management letter should be issued as soon as possible after completion of the audit procedures giving
rise to comment. This is particularly important when audit work is carried out on more than one audit visit and where
it is a matter of urgency that management make improvements to their procedures (e.g. where there is evidence of
serious weakness).
■ Clarity – wording must be clear so that recipients understand the significance of weaknesses that are being drawn to
their attention. It is particularly important that implications are explained clearly in terms that will prompt management
to respond positively (e.g. drawing attention to the risks of financial loss arising).
■ Illustrative – specific illustrative examples (e.g. of where controls have not been evidenced) should aid management in
understanding the nature of the problem(s).
■ Constructive comments/advice – recommendations for improvements must be practicable (i.e. appropriate and costeffective
in the light of the client’s resources) if the client is to take corrective action.
■ Conciseness – unnecessary volume will distract management from new/additional matters that require their attention.
For example, matters adequately dealt with in the internal auditor’s report should not be repeated.
■ Factual accuracy is essential. Inaccuracies will not only aggravate the client and appear unprofessional but could, in rare
circumstances, result in liability. Similarly, the letter should not criticise (or ‘cast aspersions’) on individual staff members
if it is the system that is inadequate.
■ A suitable structure – for example ‘tiered’, where the report contains matters of varying levels of significance. By directing
different classes of matters to the appropriate level or area of responsibility action by management can be taken more
speedily and constructively.
Tutorial note: An alternative structure might be one that sequences those recommendations that improve
profitability/cash flows before those that deal with information systems.
■ Inclusion of staff responses – both to advise senior management of action proposed/being taken by their staff and to give
credit to recommendations for improvements where it is due (e.g. where client’s staff have proposed recommendations).
■ Inclusion of management’s response – an indication of the actions that management intends to take is more likely to
result in action being taken. Discussing findings with management first should also ensure their factual accuracy.
■ Client’s perspective – implications from the client’s viewpoint (e.g. in terms of cost savings) are more likely to be acted
on than those expressed from an audit perspective (e.g. in terms of lowered audit risk).
■ Professional tone – should not be offensive. Comments that fault management’s knowledge, competence, motives or
integrity are likely to provoke defensive reactions. Comments should be positive/constructive by emphasising
solutions/benefits.
Tutorial notes: Other points that candidates may include:
■ Inclusion of matters of future relevance
■ Cost effectiveness – minutes of discussions with management instead of a formal weakness letter
■ Not raising ‘people problems’ in such a formal communication (a confidential discussion is preferable).
